IMPROVEMENT IN APPARATUS FOR EVAPORATlNG SUGAR.

Specification forming part of Letters Patent No. 33.593, dated October29, 18(11.

To all whom it may concern.-

Be it known that I, AARON H. MILLER, of La Porte, in the county of LaPorte and State of Indiana, have invented certain new and use fulImprovements in Sugar-Evaporators; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, and to the letters of reference markedthereon.

Figure 1 is a perspective view. Fig. 2 is longitudinal vertical sectionof the furnace.

A is the evaporator, and is divided into two compartments, 1 and 2, bythe strip a. The evaporator is supported at a suitable height (dependingupon the size of the furnace) from the floor or ground by .the legs a.

B is the furnace, as here represented a parallelopipedon in form.

I) are the supports or legs of the furnace, and are cleft at the bottom,so as to receive the caster-rollers 0..

d are tracks upon which the casters roll.

In operating my invention the juice is made to fill both sides of theevaporator A. The furnace B is then rolled under one of thecompartments, (see Fig. 1,) and the fire, as intense as needed, causesthe juice in the com Ipartment immediately over the furnace to boil veryrapidly until evaporated as desired, either for sugar or molasses. Thefurnace now is rolled over the track (I and on rollers c from under theone apartment until it comes immediately under the other one. The boiledjuice is then turned off from the first compartment, which is thenresupplied. Thus, by alternately rolling the furnace back and forth, theprocess of evaporating can be continued as long as may be wished withoutany waste of time, and the empty compartment can be readily cleansed ofany adhering impurities.

Having thus fully described the construction and operation of myinvention, what I claim as new, and desire to secure by Letters Patent,is-

An apparatus for evaporating saccharine liquids, so constructed that thefire-grate or furnace is adjustable under the pan to be heated, asherein set forth.
